Dünner Spaltkeil für KreissägemaschinenThin riving knife for circular saws

Die bekannten Spaltkeile weisen den Nachteil auf, daß diese häufig viel dicker sind als die Schnittfuge der Sägeblätter, einseitig gehaltert sind und somit eine geringe Steifheit aufweisen. 5The known splitting wedges have the disadvantage that they are often much thicker than the cutting gap of the saw blades, are held on one side and therefore have a low rigidity. 5

Der Erfindung liegt die Aufgabe zugrunde, ein Spaltkeilsystem zu schaffen, bei dem sehr dünne Spaltkeile mit hoher Steifheit über die gesamte Höhe und Länge einsetzbar sind.The invention is based on the object of creating a splitting wedge system in which very thin splitting wedges with high rigidity can be used over the entire height and length.

Das erfindungsgemäße Spaltkeilsystem besteht aus dünnen hochgehärteten Spaltkeilplatten, die an ihren oberen und unteren Kanten an Haltebügeln dergestalt befestigt sind, daß diese Bügel eine U-förmige Form aufweisen, um den vollen Werkstück-5 querschnitt durchlassen zu können und die in gewissen Abständen angeordnet sind, damit die Spreissel nach unten durchfallen können. Außerdem ist die Verbindung der Spaltkeilbleche mit diesen Haltebügeln so ausgebildet, daß die Spaltkeile vertikal und/oder horizontal spannbar sind. Insbesondere im Bereich der Spaltkeilvorderkante ist der Haltebügel etwa parallel zu dieser Kante angeordnet, um hier eine optimale Steifheit durch Spannung zu erzielen.The splitting wedge system according to the invention consists of thin, highly hardened splitting wedge plates which are attached to retaining brackets at their upper and lower edges in such a way that these brackets have a U-shape in order to be able to let the full workpiece cross-section through and which are arranged at certain intervals so that the splitting wedges can fall through downwards. In addition, the connection of the splitting wedge plates to these retaining brackets is designed in such a way that the splitting wedges can be tensioned vertically and/or horizontally. In particular in the area of the front edge of the splitting wedge, the retaining bracket is arranged approximately parallel to this edge in order to achieve optimal rigidity through tension.

Figur 1 zeigt den erfindungsgemäßen Spaltkeil hinter den Sägeblättern (1) mit den Vorschubwalzen (2) und dem Werkstück (3). Der Spaltkeil (4) mit seiner Vorderkante (4.1) ist etwa parallel zu dem Haltebügel (5.1) angeordnet und die Halte-Figure 1 shows the riving knife according to the invention behind the saw blades (1) with the feed rollers (2) and the workpiece (3). The riving knife (4) with its front edge (4.1) is arranged approximately parallel to the holding bracket (5.1) and the holding

bügel (5.2 und 5.3) sind in einem gewissen Abstand vorgesehen, um das Durchfallen von Spreisseln zu erleichtern.Brackets (5.2 and 5.3) are provided at a certain distance to facilitate the falling through of splinters.

Die Haltebügel (5) sind mittels der Verbindungsleiste (7) oben miteinander verbunden.The retaining brackets (5) are connected to each other at the top by means of the connecting bar (7).

Figur 2 zeigt Figur 1 gemäß Ansicht A-B mit den beiden Spaltkeilen (4), die mit den U-förmigen Haltebügeln (5) verbunden und spannbar sind, wobei die Haltebügel (5) oben durch die obere Verbindungsleiste (7) und unten durch die untere Verbindungsstange (8) verbunden sind. Die Seitenverstellung erfolgt mittels der Stellspindeln (6).Figure 2 shows Figure 1 according to view A-B with the two splitting wedges (4) that are connected to the U-shaped retaining brackets (5) and can be tightened, whereby the retaining brackets (5) are connected at the top by the upper connecting bar (7) and at the bottom by the lower connecting rod (8). The lateral adjustment is carried out using the adjusting spindles (6).
